AUTOMOBILE-HEATER.

To all' whom t may concern: I

a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Automobilev,

Heaters; `and I do hereby declare the f ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an automobile heater and has for its primary object the provision of means for accumulating air around the exhaust pipe'of the engine of the automobile so that the air will become heated and later conducted to various places within the 'automobile to warm the occupants. I

Another object of this inventlon 1s`to provide a heating drum mounted. upon the exhaust pipe of the engine and havingan air intake pipeto furnish the drum wlth air which becomes heated bythe exhaust pipe and passes through outlet pipes to various points of theautomobile for heatlng purposes.

A further object, `of this invention is to provide a radiator located 'within the ioor of the automobile and connected with the heating drum to receive hot vair therefrom l and having 4means for controlling the inlet of hotair into the radiator, whereby the heat from the radiator may be regulated.

A further object of this invention is the provision of means for connecting the steering wheel of the automobile with the drum,

whereby the steering wheel may be heated to keep the operators hands warm, obviating the danger of accidents caused by operators -hands becoming cold and unable to properly steer the automobile. A A' further objecty of this invention isl to provide a foot railing connected to the drum, whereby the foot railingv may be heated to keep the feet of the occupants of the automobile warm.

A still further object'v of this invention is the provision of an automobile heater of the above stated character, vwhich'shall be simple, durable and efhcient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in cer- Specication of Letters Patent.

nation and arrangementof parts as will be` hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which thereon a pair of externally screw-threaded collars 2 and 3,each having squared portions 4 to be engaged by a wrench for turning'the collars upon the exhaust pipe l. Substantially funnel-shaped heads '5 and 6 are threaded to the collars 2 and 3 uponl the exhaust pipe 1. A pairof cylindrical casings 7 and 8 are carried by the `heads 5 and 6 as clearly illustrated in Fig. -2 and are spaced apart to form a dead air space 9. Set screws ,11. are carried by the heads 5 and 6 for an engagement with the exhaust I 'pipe llfor securing the heads against lateral movement uponl the exhaust pipe to prevent the casings 7 and 8 from becoming detached 'from the heads. an openingat a point below the exhaust pipe 1 to receive a threaded collar 12 which is mounted upon an air intake pipe 13.- The collar 12 has an` enlarged vsquared portion '14 for the reception of a wrench for turning the collar within the opening 12 of the head 6. The air intake pipe 13` extends'jfon Wardly from the head 6 to a point adjacent the fan mounted upon the engine of the automobile (not shown) and has its end of substantially vfunnel shape as .illustrated tween the casing 8 and the exhaust pipe 1,

whereby the heat from the exhaust pipe will efliciently heatair entering from the V air intake pipe 13. An outlet pipe 16 is connected to the head 6 at a point above the exhaust pipe l and extends upwardly to 'a point adjacent the dash of the auto- A Patented Feb; 2o, 1917. Application led July 25, 1916. Serial No. 111,254.

The head 6 has y mobile (not shown) and has mounted upon its upper' end a valve 18. A branch pipe 19 is connected to the outlet pipe 16 for conducting the heated air to a radiator l0 located Within the floor board 21 of the automobile. The radiator 20 being located in the flooring between the dash of the automobile and the front seat. An outlet pipe 22 is connected to the head 5 at a point above the exhaust pipe and extends upwardly and is connected to a radiator similar to the radiator 20 and which is mounted Within the flooring of the automobile between the rear seat and the front seat for heating the occupants occupying the rear v seat of the automobile. The valve 1.8 is cony nected to lexible tubes not shown, which are in turn connected to a foot railing and to a steering wheel (not shown).

vWhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what l claim is The combination With an exhaust pipe of an engine, of relatively spaced and externally screwthreaded collars mounted on the exhaust pipe, substantially funnel shaped heads mounted on the exhaust pipe and having their restricted portions threaded to the collars, set screws threaded to the heads and engaging the exhaust pipe to prevent the collars and heads from moving on the exhaust pipe, a pair of cylindrical casings carried by the heads and Surrounding the exhaust pipe to form a heating chamber, said casings being relatively spaced on the heads to form a dead air chamber, means for admitting air to the heating chamber, and an outlet pipc connected to the heads for receiving heated air from the heating chamber.

ln testimony whereof l aflix my signature in presence of two Witnesses.
